A 500-kg ball at the end of a 30-m cable suspended from a crane is used to demolish an old building.

Part A

If the ball has an initial angular displacement of 30? from the vertical, determine its speed at the bottom of the arc.

Express your answer to two significant figures and include the appropriate units.

The horse latitudes-high-pressure zones about 30 degrees north and 30 degrees south of the equator.-warm air traveling away from the equator cools and sinks-weather tends to be clear and drythe doldrums-low-pressure near equator-air rises and spreads out toward the poles-rising moist air produces clouds and heavy rainthe westerlies-blow from the west-move from the horse latitudes toward the poles.-bring storms across much of the united statesthe tradewinds-blow from the east-move from the horse latitudes toward the equator  -strong, steady winds
